California's Lone Operating Nuclear Plant Gets Five-Year Extension | Planetizen News

The Pacific Gas and Electric Company's Diablo Canyon Nuclear Power Plant received approval from the California PUC to operate its two reactors until 2029 and 2030. Five days later, the NRC issued a temporary license renewal.

“PG&E has won approval to keep operating the aging Diablo Canyon nuclear plant in San Luis Obispo County,” reported George Avalos of the Bay Area News Group on December 14, 2023 for The Mercury News.

The five-member state
Public Utilities Commission(PUC) voted 3-0 to approve an extension of the operating license for the Diablo Canyon nuclear complex, perched near Avila Beach next to the Pacific Ocean. One commissioner was absent, while another abstained.

Diablo Canyon’s Unit 1 reactor is now slated to cease operations in October 2029 while the Unit 2 reactor will end its operations in October 2030.

Approval preordained, based on ‘energy reliability’

“The state regulatory decision to authorize the extended operations was the outcome of a September 2022 vote by the state legislature to approve SB 846— a bill signed by Newsom,” adds Avalos in the subscription-only source article.

The legislature determined that extended operations of Diablo Canyon are necessary to ensure reliable electricity supplies until more green energy sources can come online.

“ Climate change is causing unprecedented stress on California's energy system and I appreciate the Legislature's action to maintain energy reliability as the State accelerates the transition to clean energy,” wrote Gov. Gavin Newsom in his signing letter

“Energy reliability is critical to Americans’ daily lives,” notes the U.S. Department of Energy's description.

It is vital to human health, safety, and well-being and the nation’s economic prosperity and security...The effects of climate change and aging U.S.
energy infrastructure are key challenges to energy reliability.

Nuclear Regulatory Commission ruling follows

“The federal Nuclear Regulatory Commission(NRC) determined today that Pacific Gas and Electric Company's (PG&E) L icense Renewal Application(LRA) for extended operations of Diablo Canyon Power Plant(DCPP) is sufficient for its review,” notes PG&E's press release on Dec. 19.

The NRC's determination of sufficiency now allows PG&E to continue operating Units 1 and 2 at DCPP past their current licenses (2024 and 2025, respectively), while the LRA is under review.

Not to be forgotten: IIJA

Last but certainly not least, the federal bipartisan infrastructure legislation that made the 5-year extension possible, the I nfrastructure Investment and Jobs Act. See May 31, 2022 post: Extending the Life of California's Largest Power Plant.

The
passage of the Infrastructure Investment and Jobs Act(previously known as the bipartisan infrastructure framework) last November, specifically the inclusion of the $6 billion Civil Nuclear Credit Program to extend the life of nuclear power plants unable to compete with cheaper power from natural gas and renewable power facilities, influenced California Gov. Gavin Newsom's reconsideration of the decision made by PG&E six years ago to close the state's last nuclear power plant.

Accessible news report: The Santa Barbara Independent reported on Dec. 20 on both the PUC approval and NRC announcement on PG&E's Diablo Canyon Power Plant.
